inserting unicode characters into mysql database shows ??????? in field

Related searches

Hey guys I am having trouble trying to convert my web app to support unicode characters. I have the following script which tries to insert russian characters into my mysql database but just outputs ?????? in my mysql database field. I have changed default charset to UTF-8 in my php.ini and have modified my table fields to collation: utf8_unicode_ci. Anyone have any ideas?

mb_language('uni'); mb_internal_encoding('UTF-8');

                $sql = 'SET NAMES utf8';
$stmt = $conn->prepare($sql);

$sql = 'SET CHARACTER SET utf8';
$stmt = $conn->prepare($sql);

$sql = 'INSERT INTO topic (topic_id,topic_title) VALUES (?,?)';
$stmt6 = $conn->prepare($sql);

show create table edit

CREATE TABLE `topic` (
 `id` mediumint(8) NOT NULL AUTO_INCREMENT,
  `topic_title` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,

 `description` mediumtext CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,

 PRIMARY KEY (`id`),
 FULLTEXT KEY `description` (`description`),
 FULLTEXT KEY `topic_title` (`topic_title`),
 FULLTEXT KEY `topic_title_2` (`topic_title`,`description`),
 FULLTEXT KEY `description_2` (`description`)

I got it to work by using the following sql:

ALTER DATABASE mydatabase charset=utf8;

A Guide to MySQL and PHP UTF-8 Encoding, In order to insert Unicode characters in MySQL, you need to create a table with Unicode support, select the appropriate encoding/collation settings, and specify the charset in the MySQL connection. Then, you can proceed and employ PHP code to insert Unicode as you please. Character set in MySQL can have one or more collations. Character set in MySQL can be seen on the database level, table level, and column level. The default character set is “LATIN1”. Unicode character set is used to store multiple languages in a column. Character set can holdsingle-byte characters and multi-character set.

If you are seeing those ?????? on mysql browser or on mysql cli, make sure you tune up the charset settings on the programs, even if the entries are correctly added to the database, displaying them correctly also depends on the client charset settings.

JDBC: Inserting unicode UTF-8 characters into MySQL (Example), A protip by moezzie about mysql, unicode, utf8, utf-8, jdbc, java, and Just a quick heads up if you're looking to insert for example Chinese characters into a MySQL database. Case: You're using JDBC to insert strings with unicode characters from your Will you can use "setNString " as show in Example Gotcha number 1: In the latin1 character set, 'café' = 'cafe'. If you have a primary key or other unique constraint on your data, you can't insert both, and any SELECT queries for 'café' return the same results as queries for 'cafe': mysql> insert into utfail8 VALUES ('cafe'); Query OK, 1 row affected (0.00 sec)

I'm inclined to think the problem isn't with MySQL.

You are entering an non ASCII string as a literal into a PHP script. Are you sure the "дравствуйте" string will be sent to MySQL server as UTF-8 encoded?

I've seen some problems with nos ASCII characters with PHP and MySQL with incompatible charset configurations amongst the operating system, the PHP interpreter (it inherits the default from the operating system), the database and the development tools (the encoding of .php files). If all four are configured to the same encoding, it should work.

You said that your php.ini is configured to UTF-8. If your source php file isn't in UTF-8, it will not work! So, check if your php files are encoded as UTF-8 and if the mysql client is configured to UTF-8 too.

A common mistake is to forget to configure the MySQL client to UTF-8 too and fail to check the data on the database because of charset problems with MySQL client application.

Home it helps!

As of MySQL 5.6, there are Vietnamese collations for Unicode character sets, as described in Section 10.10.1, “Unicode Character Sets”. A.11.17. Does MySQL permit CJK characters to be used in database and table names? Yes. A.11.18. Where can I find translations of the MySQL Manual into Chinese, Japanese, and Korean?

UTF-8, on the other hand, can represent every character in the Unicode character set (over 109,000 currently) and is the best way to communicate on the Internet if you need to store or display any of the world’s various characters. You can specify a default character set per MySQL server, database, or table.

The Unicode terms are expressed with a prefix “N”, originating from the SQL-92 standard. The utilization of nchar, nvarchar and ntext data types are equivalent to char, varchar and text. The Unicode supports a broad scope of characters and more space is expected to store Unicode characters.

  • where are you seeing the question marks?
  • in the field topic_title in my mysql database where I am trying to insert the characters. When I echo those characters, they come out fine in php though.
  • Confused... you're seeing the question marks in your MySql CLIENT, but the data is proper unicode and prints fine through PHP when queried from the database?
  • no lol, sorry, when I view the fields in phpmyadmin, in the field where the unicode should be, it shows ???????, but when I echo those characters just in php (no query) they show. I was just trying to emphasize that the php configuration seems to be fine.
  • I have found that UTF-8 works fine without using the mb_ functions and without calling SET NAMES. Your PHP and MySQL do not necessarily need to even know that you're using UTF-8 at all. You just have to make sure the browser does, as Wrikken has noted.
  • that is true, but they are not displaying correctly in database, first it was ???????, then I removed mb_functions and calling set names like Mark mentioned and now it is дравÑтвуйте in database
  • When I said show create database, it stated ENGINE=MyISAM AUTO_INCREMENT=39 DEFAULT CHARSET=latin1, could this be a problem? Also when you mentioned converting a php file to utf-8, what exactly do you mean. Thanks again axmachado
  • I have the meta element, but when you say header, how do you modify your http setting?
  • The 'default_charset' setting should normally do, but it can't hurt to double check (for instance with LiveHTTPHeaders in Firefox).
  • Can you please add explanation how this address the issue?
  • this is unrelated to the old question at all.
